So worth it! So excited this place opened. The food is great. I really loved the small plates and the noodles. The fried rice was a little soy heavy but there are so many good things there it’s not a problem. This quickly became our new group dinner spot.

OH MY GOSH SOOOOO GOOD! Like, you think you’ve had a good all you can eat sushi experience and then you find this place. WOW. First of all, variety–amazing. With their all you can eat meal you can get dumplings, buns, wontons, chicken wings, big or small bowls of ramen, hibachi meat/veggies, rice, noodles, rice cakes, sushi, the list goes on and on. Then there’s the fact that everything we tried was SO GOOD. I kept waiting for something we ordered to come out subpar but honestly I’m like when the heck can we go back I’m already craving that hibachi steak and fresh rolls again. If you love Asian food and if you love variety, this place is your roman empire. I’ll also say the service was top-notch and the atmosphere is so fun–honestly reminds me of a place I’d been to in Japan. Just the perfect amount of random things hanging on the walls. We went for Valentine’s day and they had hung a bunch of roses everywhere, blew up balloons and were playing love songs. You can tell they care about the customer experience. All our food came out pretty quick and we didn’t feel rushed! Boba Thai tea was delicious as well. Can’t recommend enough!

KOI Ramen and Sushi
We’ve been watching this team pour months of care, craftsmanship, and detail into building out their restaurant, and the anticipation was real — and they absolutely delivered.
The food is incredible. While there are only a handful of gluten-free and dairy-free options, they are extremely accommodating, knowledgeable, and careful. Every allergy-friendly dish we had was outstanding. Our non-allergy family members have also loved everything they’ve ordered — which says a lot.
They also offer an all-you-can-eat buffet during dinner on weekdays from 4 PM to close, which has been a huge hit and definitely adds to the excitement and crowds.
The staff is professional, kind, and clearly working their tails off. We are genuinely lucky to have a place like this in our community.
Helpful tips for fellow diners:
• They are brand new and already packed — please be patient and gentle as they find their rhythm.
• Dinner lines can get long because they’ve been slammed from day one.
• The team is constantly moving at full speed trying to keep up.
• There are two restrooms, so restroom lines can form during peak hours.
• Parking is good and not an issue.
We’re so excited to watch this place continue to grow and settle in. It’s already something special. ✨

This is currently the best Japanese restaurant I’ve experienced! So happy to have found such a delicious Japanese restaurant here! I’ve been to Japan many times, and the quality of the food here is excellent! The service is also fantastic! I will definitely come back again!

Food: We tried the AYCE menu and I ordered a few appetizers. The seaweed salad and takoyaki were high quality and had a good flavor. Some of the others (like the egg rolls and wontons) had a cheap feel & flavor to them, which is expected I guess at AYCE places, though. All of the sushi rolls I tried I enjoyed a lot and they were all good quality. The fish was fresh, the sauces were good, and they had a pretty presentation. All of the flavor combinations were delicious, too, with some notable ones being the mango tango and Hawaii rolls.
Service: Everyone was welcoming and kind. There were a few kinks in the service, though, such as several waiters asking to take our orders or asking if we had this roll that someone else ordered. I understand it’s opening week however and I won’t ding them for that. They’re doing their best with what they have right now and I appreciate it.
Ambiance: It was small width wise, but had a long space, and the interior was cute. You could see the kitchen and the roll station, and the bar area. There were cute bubble tanks and neon light up signs which boosted the experience.
Overall: For opening week it was pretty good food and service, but they just need to fix a few issues, which I’m sure they will as they get more used to it.

The food was great. We did the all you can eat dinner, this allowed us to try what we wanted. I loved that items were served in a small portion for this menu. Service seemed to be a bit scattered; multiple people taking orders or attempting to bring unordered items…. chalked it up to the resturant just opening. Very excited to go back again.
Pictured… shaggy dog roll; shrimp tempura, crab meat, and avocado. Delicious!!

Absolutely wonderful! They had friendly and courteous service. The restaurant was clean. Plenty of seeding plus a bar for cocktails and beers. The food was fantastic. I had the ramen and fried sushi. It was delicious. They even box it for you and these very nice to go plastic containers that are keepable and your food stays nice and doesn’t spill in your car and leak all over in the bag. And they do it for you so you don’t have to make a mess at the table. This is a must try in Johnstown proper on 60th at the ledge Rock

The menu has a lot of great ramen and sushi options, as well as beverages. We both had ramen and it was great! We also had the potato croquettes, which were tasty!
The staff was incredibly focused on making sure our experience was a good one.
The atmosphere was hip and modern.

What a pleasant surprise to be invited to a secret soft opening of Koi tonight and be the very FIRST table served at the brand new Koi Ramen & Sushi restaurant in Johnstown, CO.
The cliff note/TLDR version is that Koi is a must-try affordable AYCE sushi, nigiri, skewer, ramen, hibachi and asian appetizer restaurant; with some of the very best quality food in all of northern Colorado. Many of the flavors from Bowl Izakaya in west Loveland will shine through which immediately made me happy! Koi is like Bowl Izakaya in Loveland and Chubby Fish in Thornton had a baby and I was NOT disappointed! Koi is conveniently located off I-25 in the new Ledge Rock complex next to Firehouse Subs and in the same lot as Wood’s Supermarket.
Walking in you are greeted by a giant cat to your left that is waving and welcoming you in. They have a very large beautifully designed bar with what appears to be seating on both the wet bar side and the sushi making side. The vibe is very modern and the music choice tonight was old school rock and roll which was excellent! Several tables of all sizes surroud the bar and in some areas of the restaurant you have clear visibility to one of the most beautiful kitchens I have ever seen.
Our party all choose the all you can eat dining option. The staff all encourage you to try everything on the menu as many times as you like! Be sure to pay close attention to how many pieces come in a single order when ordering for the group. Most of this info is found on the menu but if you dont know, just ask. We indulged in every available option and some several times. The food was fresh, flavorful, plentiful and outstanding and you will not be disappointed!
After we got there a few others walked in and dined in as well. The restaurant was far from capacity but i believe service will be excellent because I observed lots of staff working in unity with one obvious single purpose, pleasing you, the customer. The service was a true delight!
PSA – if you are a fan of the new style AYCE Ramen & Sushi restaurants and live in northern Colorado or the surrounding area, you no longer need to drive to Denver! We now have one of the best in our backyard!
In summary, Koi officially opens tomorrow 1-12-26 and you deserve this culinary treat! One things for certain, my tribe and I will be there again real soon and I hope to see you there!!!
Great job Koi Team and welcome to Johnstown!!!
